Abstract
Ginkgo biloba, known as the “living fossil,” has a long history of being used as botanical drug for treating cardiovascular diseases and the content of flavonoids as high as 24%. More than 110 different kinds of flavonoids and their derivatives have been separated from G. biloba, including flavones, flavonols, biflavonoids, catechins, and their glycosides, etc., all of which display the ability to dilate blood vessels, regulate blood lipids, and antagonize platelet activating factor, and protect against ischemic damage. At present, many types of preparations based on G. biloba extract or the bioactive flavonoids of it have been developed, which are mostly used for the treatment of cardiovascular diseases. We herein review recent progress in understanding the metabolic regulatory processes and gene regulation of cellular metabolism in cardiovascular diseases of G. biloba flavonoids. First, we present the cardioprotective flavonoids of G. biloba and their possible pharmacological mechanism. Then, it is the pharmacokinetic and liver and gut microbial metabolism pathways that enable the flavonoids to reach the target organ to exert effect that is analyzed. In the end, we review the possible endogenous pathways toward restoring lipid metabolism and energy metabolism as well as detail novel metabolomic methods for probing the cardioprotective effect of flavonoids of G. biloba.

Abstract
Drug-metabolizing enzymes, particularly the cytochrome P450 (CYP450) monooxygenases, play a pivotal role in pharmacokinetics. CYP450 enzymes can be affected by various xenobiotic substrates, which will eventually be responsible for most metabolism-based herb–herb or herb–drug interactions, usually involving competition with another drug for the same enzyme binding site. Compounds from herbal or natural products are involved in many scenarios in the context of such interactions. These interactions are decisive both in drug discovery regarding the synergistic effects, and drug application regarding unwanted side effects. Herein, this review was conducted as a comprehensive compilation of the effects of herbal ingredients on CYP450 enzymes. Nearly 500 publications reporting botanicals’ effects on CYP450s were collected and analyzed. The countries focusing on this topic were summarized, the identified herbal ingredients affecting enzyme activity of CYP450s, as well as methods identifying the inhibitory/inducing effects were reviewed. Inhibitory effects of botanicals on CYP450 enzymes may contribute to synergistic effects, such as herbal formulae/prescriptions, or lead to therapeutic failure, or even increase concentrations of conventional medicines causing serious adverse events. Conducting this review may help in metabolism-based drug combination discovery, and in the evaluation of the safety profile of natural products used therapeutically.

Abstract
OBJECTIVE The objective of this study was to investigate the efficacy and safety of Ginkgo biloba preparation for the treatment of Alzheimer disease (AD). METHODS Both English (PubMed, Embase, Cochrane Library databases, and the Cochrane Controlled Trials Register) and Chinese (WanFang, Chinese Biomedical, CNKI, and VIP databases) databases were systematically and independently searched by 2 authors from their inception until July 3, 2019. All relevant studies included AD patients who were treated with Ginkgo biloba. The efficacy and safety of the medicine were used as the main measurement index. RESULTS Seven studies (N = 939) were identified and analyzed. When compared with placebo, Ginkgo biloba showed exact validity in cognitive function and global clinical assessment (cognitive function section: risk ratio = 1.98, 95% confidence interval = 1.52-2.59, Z = 5.12, P < 0.001; according to Clinical Global Impression Change: odds ratio = 3.119, 95% confidence interval = 2.206-4.410, Z = 6.44, P < 0.001). Adverse events were mild. CONCLUSIONS Ginkgo biloba preparation has reliable efficacy of cognitive function and global clinical assessment and safety in the treatment of AD.

Abstract
The inflammatory immune response (IIR) is a physiological or excessive systemic response, induced by inflammatory immune cells according to changes in the internal and external environments. An excessive IIR is the pathological basis for the generation and development of neurological diseases. Ginkgolides are one of the important medicinal ingredients in Ginkgo biloba. Many studies have verified that ginkgolides have anti-platelet-activating, anti-apoptotic, anti-oxidative, neurotrophic, and neuroimmunomodulatory effects. Inflammatory immunomodulation is mediated by inhibition of the mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-κB) signaling pathways. They also inhibit the platelet-activating factor (PAF)-mediated signal transduction to attenuate the inflammatory response. Herein, we reviewed the studies on the roles of ginkgolides in inflammatory immunomodulation and suggested its potential role in novel treatments for neurological diseases.

Abstract
INTRODUCTION Cytochrome P450 (CYP) families 1 - 3, besides oxidizing environmental and dietary chemicals, leading to their elimination, catalyze the bioactivation of exogenous as well as endogenous carcinogens. Phytochemicals, particularly those which are active food components, were shown to be able to affect specific CYP expression and/or activity in animal models and in human in vitro systems. Human intervention studies involving healthy volunteers were also performed. This review describes human CYP modulation by naturally occurring phytochemicals which can not only affect carcinogen metabolism in humans, but also change the drug response. AREAS COVERED The authors present an overview of carcinogens metabolizing human CYP modulation in different model systems as well as studies on human dietary intervention. Furthermore, the authors provide examples of the phytochemicals that affect CYP expression and activity. EXPERT OPINION CYP, which are involved in carcinogen activation, can metabolize a range of substrates and inducing CYP by one substrate may also increase the metabolism of another. The ultimate proof of the efficacy of CYP modulation strategy for chemoprevention may be provided by clinical trials involving risk populations, which are difficult to perform. The new human-like models are highly desired for the study of modulation of carcinogen-metabolizing CYP.

Vrba J, Kren V, Vacek J, Papouskova B, Ulrichova J. Quercetin, quercetin glycosides and taxifolin differ in their ability to induce AhR activation and CYP1A1 expression in HepG2 cells. Phytother Res 2012; 26:1746-52. [PMID: 22422552 DOI: 10.1002/ptr.4637] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2011] [Accepted: 01/23/2012] [Indexed: 11/08/2022]
Abstract
The natural flavonoid quercetin is a low affinity ligand of the aryl hydrocarbon receptor (AhR), a transcription factor regulating the expression of cytochrome P450 (CYP) 1A enzymes. This study examined the ability of quercetin, isoquercitrin (quercetin-3-O-glucoside), rutin (quercetin-3-O-rutinoside) and taxifolin (dihydroquercetin) to activate AhR and to induce CYP1A1 expression in human hepatoma HepG2 cells. Gene reporter assays showed that quercetin significantly activated AhR and triggered CYP1A1 transcription after 24 h exposure. These effects were, however, much lower than those of 2,3,7,8-tetrachlorodibenzo-p-dioxin, a prototypical AhR ligand. Quercetin also induced a significant increase in CYP1A1 mRNA levels together with a moderate increase in the level of CYP1A1 activity. In contrast, isoquercitrin and rutin had negligible effects on AhR activity and CYP1A1 expression. Taxifolin at the highest concentration tested (50 µm) produced a mild non-significant increase in AhR activity and CYP1A1 transcription. Taxifolin also significantly increased CYP1A1 mRNA expression, but this effect was approximately 15 times weaker than that of quercetin and was not accompanied by induction of CYP1A1 activity. It is concluded that quercetin, but not its 3-O-glycosides isoquercitrin and rutin, induces AhR activation and CYP1A1 expression in HepG2 cells and that the CYP1A1-inducing activity of taxifolin has a low toxicological potential.
